That keyed my interest in looking at some old digital photos of my 3 stage
septic tank being installed here a few years ago. It was on a specialized
truck with motorized winch. Entire septic tank is coated in concrete with
flat top. Although small in relative size as far as septic tanks go, it was
pretty big at 1500 gallons total.

I'm guessing you meant the company that made a septic tank from those
individual tanks is where you got those 2 tanks.

CDOs are how we got here.
A modified version, new taxes in the future, is how Congress will get us
out?

I had two 500 gallon holding tanks for rain water. They were fiberglass and
I could see the water turning lovely shades of green as the summer
progressed. Didn't hurt a thing. You're only using it to water your plants,
right? I did toss in a few feeder gold fish every year as soon as the temp
was above 50°. They are excellent, non toxic skeeter control. I never fed
the fish and they thrived until I emptied the tanks in the fall before the
hard freeze.

BTW, if you are looking for a very inexpensive holding tank check out
septic tank companies. I got two 500 gallon septic tanks for $20 each.
They had been cracked when delivered to this company so couldn't be used
for the intended purpose but I just got a patch kit and fixed the cracks
when I got them home. Worked great.

Here in So. Calif, we have had drought conditions for several
years, so now that we are having some rain, am saving every drop of
rainwater I can. I now have a large barrel full, and more may be on
the way - I hope!

Question: How long can I "safely" keep the barrel full
of H2O? Without breeding mosquitos, worst case, or..?

Is it necessary to put some chlorine in, and if so,
how much would be safe for the plants.

This may all be overkill; if we just don't get any more
rain, it will get used up fast. Have been curious about
this for some time, so turning to Your Wisdom g
